Following the launch of the higher density analogue modules for the Idec PLC Pentra and MicroSmart range, Idec has also upgraded the original two and three channel analogue and thermocouple modules
These modules are available in the following combinations: (two in/one out voltage/current), (two in voltage/current), (two in thermocouple/resistance thermometer, one out voltage/current) (one out voltage/current).
Significant improvements have been made in the sampling duration time, (20ms down to 10ms), the total input system transfer time (105ms down to 60ms), and the total output system transfer time, (50ms down to 10ms).
Also the resolution of the thermocouple module has been improved from 12 to 14 bits, giving an accuracy of one part in 16,384.
Finally, the electrical noise tolerance level has also been improved when subjected to electrical noise, which means the modules are less susceptible to interference when operating in harsh environments.
The end result of these upgrades is that the speed of movement of analogue data into and out of the MicroSmart or Pentra programmable controller has considerably increased meaning that the update time of analog data need no longer be an issue in certain applications.
Faster response means greater accuracy of analogue data.
These new products are recognized by having V.200 firmware version identified on their labels.
